Denis L.

Customer service rep

Pros

“ZeroBounce offers easy setup, strong spam detection, great support, and good value for teams.team collaboration features that make managing and verifying email lists efficient across departments.”

Bhanu L.

Growth

“It made list hygiene easier by quickly identifying obvious bad addresses and highlighting risky segments (spamtraps/abuse/unknown). Once you define internal rules for how to treat catch-all and other edge cases, it becomes a strong, repeatable part of an email deliverability workflow.”

Connor C.

Director, Email

“I think its a powerful tool to help companies reduce their spam when prospecting new regions, helping emails to stay safe from spam folder”

Alvaro S.

Owner

Cons

“The marketing campaign features are not as advanced as some dedicated email marketing platforms.”

Denis L.

Customer service rep

“The pricing levels are not worth the money because our e-commerce traffic is at its peak, and customer service is painfully slow when we have urgent account problems or some data management failures.”

Amir H.

E-Commerce Manager

“I’ve run into bugs that the support team hasn’t been able to help with and often feel limited by the automation capabilities.”

Hayley A.

Marketing Manager

Cons

“In particular, the account verification emails were unreliable, the verification link consistently failed, making it difficult to complete the registration process.”

Rishav K.

GTM Engineer

“Additionally, some of the validation categories require interpretation, which can create minor uncertainty around borderline results if you are new to email verification tools.”

Finn J.

CEO

“When listing emails, the system is unable to smartly identify and predict points of errors such as omission of domain name or '@' symbol on each line”

Paul A.

Executive Officer
